       1. A method for performing a communication on a specific single secondary cell (SCell) in a wireless communication system supporting carrier aggregation (CA), the method comprising:
 receiving configuration information of multiple frequency zones constructing the specific single SCell, 
 wherein a primary cell (PCell) is allocated to a licensed band and the specific single SCell is allocated to an unlicensed band, 
 wherein the configuration information indicates one or more available frequency zones and zero or more unavailable frequency zones included in the multiple frequency zones, and 
 wherein the one or more available frequency zones and the zero or more unavailable frequency zones are determined based on a frequency occupation of another system; and 
 performing the communication on the specific single SCell, 
 wherein the configuration information is applied only to a reference signal transmission for the communication, and 
 wherein the reference signal transmission for the communication is dropped when a band of the reference signal transmission is overlapped with an unavailable frequency zone on the specific single SCell based on the configuration information. 
 
     
     
       2. The method according to  claim 1 , wherein the unlicensed band includes a TV whitespace band. 
     
     
       3. The method according to  claim 1 , wherein the wireless communication system is a 3rd Generation Partnership Project (3GPP) wireless communication system. 
     
     
       4. The method according to  claim 1 , wherein the multiple frequency zones constructing the specific single SCell are configured to operate on a specific frequency range. 
     
     
       5. The method according to  claim 1 , wherein the multiple frequency zones constructing the specific single SCell are processed using at least one of a single Discrete Fourier Transform (DFT) process and a single Inverse Discrete Fourier Transform (IDFT) process. 
     
     
       6. A communication device configured to perform a communication on a specific single secondary cell (SCell) in a wireless communication system supporting carrier aggregation (CA), the communication device comprising:
 a radio frequency (RF) unit; and 
 a processor configured to:
 control the RF unit to receive configuration information of multiple frequency zones constructing the specific single SCell, 
 wherein a primary cell (PCell) is allocated to a licensed band and the specific single SCell is allocated to an unlicensed band, 
 wherein the configuration information indicates one or more available frequency zones and zero or more unavailable frequency zones included in the multiple frequency zones, and 
 wherein the one or more available frequency zones and the zero or more unavailable frequency zones are determined based on a frequency occupation of another system, and 
 control the RF unit to perform the communication on the specific single SCell, 
 
 wherein the configuration information is applied only to a reference signal transmission for the communication, and 
 wherein the reference signal transmission for the communication is dropped when a band of the reference signal transmission is overlapped with an unavailable frequency zone on the specific single SCell based on the configuration information. 
 
     
     
       7. The communication device according to  claim 6 , wherein the unlicensed band includes a TV whitespace band. 
     
     
       8. The communication device according to  claim 6 , wherein the wireless communication system is a 3rd Generation Partnership Project (3GPP) wireless communication system. 
     
     
       9. The communication device according to  claim 6 , wherein the multiple frequency zones constructing the specific single SCell are configured to operate on a specific frequency range. 
     
     
       10. The communication device according to  claim 6 , wherein the multiple frequency zones constructing the specific single SCell are processed using at least one of a single Discrete Fourier Transform (DFT) process and a single Inverse Discrete Fourier Transform (IDFT) process.
